Great pipe

The Pipe fit perfect and the 3 piece design is definitely better then the 2 piece that came on my 2018 Ktm450. Now I do not have to remove the shock to take off the pipe. Performance is better then stock but Not night and day but that is what I expected. KTM pipes are really good to start with. No complaints and would recommend to anyone.

Nice buy

purchased for my 2016 ktm 350 sxf and it really opened it up. gave it so much more bottom end and mid range power. sounds awesome as well.

Tricky install

Purchased for a 2016 350 sx-f and took a good deal to get it to fit right. But other than that great exhaust and nice power boost

Works better than expected

It's worth purchasing this header for the weight reduction alone, but 3 extra HP is noticeable.

Motosport was out of the header and pipe together--on backorder for 4 months! so I had to purchase separate at $50 more. Bummed about that!

Q: Can this be installed with a stock silencer?

Q: 2010 kx450f. Full ti 4.1 fmf with mega bomb. Previous owner broke mega bomb weld. I was going to replace with a cheaper power bomb instead of 'mega' bomb. On install I noticed power bomb header is smaller diameter than slip on. Will that expand with heat

A: The headers sound not expand so much that it would close a gap. They should fit fairly snug together if they are they correct fit.
Q: Is this fit on a KTM 450 EXC-F 2018 if it fit on a 450 SX 2018?

A: The FMF Megabomb Header With Mid Pipe is specifically designed to work with FMF mufflers.
Q: Does anyone know performance increases from a full akrapovic system to using the FMFs? Bike is 2016 KTM 450sxf factory edition.

A: We have no way of knowing performance increase differences between the two company's products. You would need to contact each manufacturer and request the stats for each of the items, for that particular model of bike.
Q: Exhaust

What’s the difference in the SX style and regular style? Also are both MX AND standard both titanium or no?

A: The SX/MX is primarily for KTM and you'll get either SX or MX based on the model bike you have. For any other brand bike it would just be considered standard and you'll have the option of stainless steel or titanium for material. Basically same pipes.
Q: Sx style vs. standard
2 years 11 months ago
I have a 2016 SXF 350, I've been trying to figure out the difference and have been having a hard time filtering through the nonsense. I was wondering what the difference was between the sx style and the standard style option for my bike. Is one better for low end?
Q: Can i put the Mega Bomb Header with my stock exhaust

A: Unfortunately, No. The FMF Megabomb Header will only work with FMF Mufflers/Mid-pipes. The diameter of this header would be too large to fit your stock muffler.
Q: Can i use DR.D muffler with it?

A: No. This FMF Mega Bomb Header is only compatible with FMF Slip-On Mufflers. It will not work with the DR. D Slip-On.
Q: Hello i was wondering if this exhaust combined with the fmf Q4 would be loud?
Over 6 years ago
I have an lrd exhaust and its way to loud so looking for something that is very quiet thank you

A: The Q4 muffler is one of the quietest mufflers available. It will be much quieter than your current LRD system. This header will work great with the Q4 muffler and will not add any additional noise.
